Nobody will claim heart/fighter/warrior. Why? Because clay is EASY for Nadal. Even at 50% health, it was EASY for Nadal to win 4 clay titles. That's why he's the only slam GOAT in history.

The AO has 2 leaders. Wimbledon has 2 leaders. The US Open has 3 leaders. Roland Garros is the only slam with an outright leader - Rafael Nadal 7 RG titles (and only one loss). Be grateful that there is a slam GOAT.
